Description
This class implements a simple counter, which provides atomic operations that are safe to use in a multithreaded environment.
Typical usage of AtomicCounter is for implementing reference counting and similar functionality.
Member Summary
Member Functions: operator !, operator ++, operator --, operator =, operator ValueType, value
Types
ValueType
typedef int ValueType;
The underlying integer type.
Constructors
AtomicCounter
Creates a new AtomicCounter and initializes it to zero.
AtomicCounter
explicit AtomicCounter(
ValueType initialValue
);
Creates a new AtomicCounter and initializes it with the given value.
AtomicCounter
AtomicCounter(
const AtomicCounter & counter
);
Creates the counter by copying another one.
Destructor
~AtomicCounter
~AtomicCounter();
Destroys the AtomicCounter.
Member Functions
operator ! 
bool operator ! () const;
Returns true if the counter is zero, false otherwise.
operator ++
ValueType operator ++ ();
Increments the counter and returns the result.
operator ++
ValueType operator ++ (
int
);
Increments the counter and returns the previous value.
operator --
ValueType operator -- ();
Decrements the counter and returns the result.
operator --
ValueType operator -- (
int
);
Decrements the counter and returns the previous value.
operator =
AtomicCounter & operator = (
const AtomicCounter & counter
);
Assigns the value of another AtomicCounter.
operator =
AtomicCounter & operator = (
ValueType value
);
Assigns a value to the counter.
operator ValueType
operator ValueType() const;
Converts the AtomicCounter to ValueType.
value
ValueType value() const;
Returns the value of the counter.
